<strong>HCV</strong> – Extrahepatic Manifestations:<br />

<strong>Pruritus</strong> (<strong>Itching</strong>)<br />

CD Mazoff, PhD, Managing Editor<br />

<strong>Pruritus</strong> is one of the most common symptoms<br />

reported by people with hepatitis C (20%), but<br />

is more commonly found in people with advanced<br />

liver disease and cirrhosis. <strong>Pruritus</strong> is<br />

itching that may be localized to a specific part<br />

of the body such as hands and feet, but it can<br />

also be a generalized itching all over the body.<br />

Some people even report that it feels like their<br />

internal organs itch. <strong>Pruritus</strong> can be related to<br />

high bilirubin levels, autoimmune disease or dry<br />

skin, and can be a side effect of treatment. Use<br />

of moisturizing lotions, oatmeal baths or lotions,<br />

antihistamines, and cortisone creams and opiate<br />

drugs can help.<br />

Recent studies are showing that dermatologic manifestations,<br />

and pruritus in particular, may be the only sign of<br />

chronic <strong>HCV</strong>; therefore it is important that health care<br />

professionals be aware of extrahepatic dermatologic<br />

manifestations, of which pruritus is an example.* Experts<br />

believe pruritus in people with liver disease is due to the<br />

accumulation of toxins (such as bilirubin) that are not<br />

effectively processed or filtered by the damaged liver.<br />

One function of the liver is the production of bile, which<br />

helps digest fats. Cholestasis, or blockage of the flow<br />

of bile through the liver, can result in a build-up of bile<br />

acids and bilirubin in the blood. High bilirubin levels cause<br />

jaundice (yellowing of the skin and eyes), and pruritus is<br />

common in people with jaundice. Certain extrahepatic<br />

(outside the liver) conditions associated with <strong>HCV</strong>, such as<br />

autoimmune conditions, may also lead to itching. More<br />

commonly, itching due to dry skin can be a side effect of<br />

treatment with interferon/ribavirin; this is not the same<br />

as pruritus due to advanced liver damage.<br />

<strong>Pruritus</strong> symptoms can range from annoying mild itching<br />

to severe itching that interferes with daily life. Often the<br />

itching is worse at night, and may prevent sleep. Simple<br />

scratching typically does not relieve pruritus. As a result,<br />

some people risk skin infection and injury by scratching<br />

themselves with sharp objects.<br />

Certain drugs can help reduce itching, particularly classical<br />

analgesics for neuropathic pain (gabapentin, antidepressants)<br />

which also exhibit antipruritic efficacy upon<br />

clinical use. Some people find that antihistamines, such<br />

as diphenhydramine (Benadryl) or hydroxyzine (Atarax),<br />

help relieve symptoms and allow better sleep.<br />

For pruritus due to cholestasis, cholestyramine (Questran)<br />

and colestipol (Colestid) may be effective. These drugs<br />

are bile acid binders that attach to bile acids in the blood<br />

and help eliminate them from the body. They can also<br />

interfere with the absorption of other medications, so<br />

other drugs should be taken at least two hours before or<br />

after bile acid binders.<br />

Some studies have shown that opiate antagonists such<br />

as naloxone (Narcan), naltrexone (Revia), and nalmefene<br />

(Revex)–which are used to block the effects of opiate<br />

drugs–can also reduce severe itching. Phenobarbital<br />

(Luminal), ondansetron (Zofran), and ursodiol (Actigall)<br />

may also be used, and several other medications are<br />

under study.<br />

Rifampin, a hepatic enzyme inducer, is effective for the<br />

pruritus of cholestasis, but caution should be used in patients<br />

with preexisting liver disease because of possible<br />

hepatotoxicity. Butorphanol has also been shown to<br />

be effective in suppressing cholestatic pruritus. Zoloft<br />

(Sertraline), an antidepressant often prescribed to people<br />

with hepatitis C, is also effective in reducing the itching<br />

caused by cholestatis.<br />

Another way to reduce itching is to stop smoking if you do<br />

smoke tobacco. Not only does smoking possibly affect the<br />

sustained virological response to interferon (IFN) therapy,<br />

but it can also lead to “Smoker’s Syndrome,” which is<br />

characterized by episodes of facial flushing, warmth of the<br />

palms and soles of feet, throbbing headache, fullness in<br />

the head, dizziness, lethargy, prickling sensation, pruritus<br />

and arthralgia (joint pain).<br />

Experimental treatments for pruritus include plasmapheresis<br />

(in which blood plasma is removed, filtered, and<br />

returned to the body) and ultraviolet (UV) light therapy.<br />

Liver transplant is the only cure for severe itching in<br />

people with advanced liver disease. For most people<br />

with less advanced hepatitis C, though, practical measures<br />

and medications are often sufficient to overcome<br />

the itch.<br />

Tips for combating dry skin and itching:<br />

♦♦<br />

Avoid soap. Use a non-soap cleanser such as<br />

Cetaphil or a similar substitute<br />

♦♦<br />

Try rubbing, vibration, or applying pressure instead<br />

of scratching. A good thing to “scratch” with is an<br />

ice cube<br />

♦♦<br />

Drink plenty of water or other clear fluids to keep your<br />

entire body hydrated<br />

♦♦<br />

Apply moisturizer immediately after a shower or bath<br />

– before drying off with a towel<br />

♦♦<br />

Creams are more effective moisturizers than lotions<br />

♦♦<br />

Apply moisturizer at least twice a day. Effective<br />

moisturizers include Vaseline Intensive Care, Aveeno,<br />

Eucerin, and Lubriderm<br />

♦♦<br />

Use only non-perfumed, mild bath and personal care<br />

products<br />

♦♦<br />

Avoid extremely hot showers and baths<br />

♦♦<br />

Take an oatmeal bath to relieve itching and help with<br />

relaxation<br />

HCSP • VERSION 2.2 • June 2010<br />

♦♦<br />

Try baking soda or unscented bath oils for bathing<br />

♦♦<br />

Apply cold packs (wrapped in a towel) to the skin<br />

♦♦<br />

Whenever possible, wear loose fitting clothes made<br />

from natural fabrics that breathe<br />

♦♦<br />

Protect your skin from the sun – wear sunscreen<br />

♦♦<br />

Look after your lips – use lip balm with sunscreen<br />

♦♦<br />

Get plenty of rest<br />

♦♦<br />

Keep rooms ventilated and at a temperature of 60<br />

to 70 degrees<br />
